Beyoncé debuts '50 Shades of Grey' teaser

Beyoncé’s Instagram isn't just for sexy, stylish selfies anymore. (Say that three times fast.)

The superstar has used her account to give America its first look at next year's " 50 Shades of Grey."

On Saturday, Bey posted a 15-second teaser for the movie's trailer. The full trailer will be released Thursday.

The video teaser included just four shots. The first is of a business man looking out an office window with his back to camera. Next, a close-up of a man tapping his fingers. Then a close-up of a woman's legs as she pulls up her skirt a little and finally a man unlocking a door.

A grainy version of Beyoncé’s "Crazy in Love" plays in the background of the teaser.
